The cotton swab has been around for just over a century. In that time, it has gone from a handmade baby care product to one of the most ubiquitous single-use items on earth — and from a solution to a problem. Here is the full story.
The Invention: Leo Gerstenzang, 1923
The cotton swab was invented by Leo Gerstenzang, a Polish-American entrepreneur, in 1923. The origin story is one of those neat, domestic moments that launched an industry: Gerstenzang observed his wife attaching small pieces of cotton wool to toothpicks to clean around their baby's eyes, ears, and nose. He recognised an opportunity to manufacture a ready-made, consistent version of what she was improvising at home.
He founded the Leo Gerstenzang Infant Novelty Co. in New York and began producing what he called "Baby Gays" — cotton-tipped applicators initially marketed exclusively for infant care. The product was positioned as safer and more hygienic than the improvised toothpick-and-cotton method, and it sold well in the US market throughout the 1920s.
From Baby Gays to Q-Tips
In the late 1920s, Gerstenzang rebranded the product as Q-tips, with the Q standing for "quality". The rebrand coincided with a broadening of the marketing — no longer just for babies, but for adults too. By the 1930s, Q-tips were being marketed for makeup application, first aid, and general household cleaning tasks.
The product that Gerstenzang designed was not intended for ear canal cleaning. The original marketing materials show uses around the outside of the ear — cleaning the outer folds — not insertion into the canal. The ear-cleaning association that would come to define the product was, in a sense, a cultural drift from the original use case.
The Ear-Cleaning Paradox
By the mid-20th century, cotton swabs had become synonymous with ear cleaning in popular culture, despite never being designed for it. Medical professionals began raising concerns about ear injuries linked to swab use from the 1950s onward. The American Academy of Otolaryngology issued guidance advising against inserting swabs into the ear canal.
Manufacturers responded by adding the now-familiar warning label: "Do not insert into ear canal." It has been printed on Q-tips boxes for decades. It has not significantly changed behaviour. Studies consistently show that the majority of cotton swab users use them to clean their ears, despite the warning.
This paradox — a product warning against its most common use — is one of the stranger chapters in consumer product history.
A Century of Scale
Q-tips was acquired by Chesebrough-Pond's in 1987, and subsequently by Unilever in 1987, where it remains today as the dominant cotton swab brand in the United States. Globally, dozens of regional brands produce functionally identical products — cotton tips on plastic or paper stems, individually disposable.
Over 100 years, the humble cotton swab scaled from a handmade novelty to a multi-billion unit annual market. The environmental consequences of that scale only became apparent over decades: billions of plastic-stemmed swabs in landfill and waterways, appearing consistently in ocean clean-up surveys and marine environmental reports.
The Beginning of a Different Chapter
The first serious regulatory response came in 2019, when the EU adopted its Single-Use Plastics Directive, banning plastic-stemmed cotton buds among a range of other single-use plastic items. The ban came into force across EU member states in July 2021. The UK introduced equivalent legislation separately after Brexit.
The shift from plastic to paper stems addresses part of the problem — the persistent plastic in waterways — but not the structural one: billions of single-use items still being produced and discarded daily.
That structural problem is what led to the creation of LastSwab — a reusable silicone alternative designed to replace a habit rather than just improve the materials of a disposable. One hundred years of the cotton swab is enough history. Read the complete guide to reusable cotton swabs to understand where things go from here.
